UISegmentedControl和本地化字符串

Question

我有一个带有3个段的UISegmentedControl。英文字符串非常合适，但西班牙语字符串稍微长一些，而不是。

动态操作字体大小以使字符串适合段大小的正确步骤是什么？是否有类似于minimumFontScale的{​​{1}}属性的内容？

Answer 1

尝试这个

[_segmentedControl.subviews enumerateObjectsUsingBlock:^(UIView * obj, NSUInteger idx, BOOL *stop) {
    [obj.subviews enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
        if ([obj isKindOfClass:[UILabel class]]) {
            UILabel *lblCaption = (UILabel *)obj;
            lblCaption.minimumFontSize=10.0f;
//OR
            lblCaption.minimumFontSize = 0.5f;
        }
    }];     
}];

Answer 2

试试这个 您不需要设置任何最小字体大小。如果需要，它将自动更改字体大小以显示标题。
